Patent number: 5275040Abstract: Gas influx into a wellbore, which is commonly referred to as a "kick", is detected during active drilling of the borehole. In a preferred embodiment of the invention a determination of mud pump noise round trip transit time T by evaluating a function T=(n-.PHI./2.pi.)f where .PHI. is the phase between standpipe and annulus signals and f is the frequency of a drill fluid oscillation caused by a mud pump and n is an integer which is incremented or decremented until the rate of change of T with respect to frequency is zero. An alarm signal is generated when the rate of change of T with respect to time exceeds a predetermined threshold. In another embodiment of the invention a determination of the Doppler frequency shift of a mud pump signal expressed as a ratio signal, .DELTA.f/f.sub.0 where .DELTA.f is the change in frequency measured at the annulus from the frequency f.sub.0 of the mud pump signal measured at the standpipe.Type: GrantFiled: June 11, 1991Date of Patent: January 4, 1994Assignee: Anadrill, Inc.Inventor: Daniel Codazzi

Patent number: 5154078Abstract: Gas influx into a wellbore, called A "kick", is detected by two different, yet complementary methods during active drilling of the borehole. The first method is based upon the existence of standing wave patterns generated by pressure oscillations of the drilling rig mud pumps. Such standing wave patterns form time sequences of maximum and minima as a gas slug moves upwardly in the annulus. The time between such peaks of such oscillations is measured and forms the basis for generation of one first kick signal. A continuous increase in the phase between annulus and drill string standing waves forms the basis for another standing wave kick signal. The second method uses acoustic signals from a downhole source near the bottom of the borehole which are transmitted at different speeds in the annulus mud and in the interior drill string mud, where the annulus mud may be gas cut. A difference in arrival time between the signals is determined, and if large enough, causes a second kick signal to be generated.Type: GrantFiled: June 29, 1990Date of Patent: October 13, 1992Assignee: Anadrill, Inc.Inventor: Daniel Codazzi

Patent number: 4920795Abstract: The invention is a non-intrusive system for measuring the flow rates of insulating or conducting fluids in conduits. It results from the combination of an electromagnetic flowmeter, operating with conducting fluids, and of a triboelectric noise cross-correlation flowmeter, operating with insulating fluids. The system is equipped with a non-intrusive device for measuring fluid conductivity. The electronic signal processing unit uses the conductivity value to decide which of the two sensors is providing a signal effectively representing the fluid flow rate. The electromagnetic flowmeter may use electrodes of small cross-section in contact with the fluid or, more advantageously, it may be of the capacitive type using larger section electrodes isolated from the fluid.Type: GrantFiled: November 19, 1987Date of Patent: May 1, 1990Assignee: Dowell Schlumberger IncorporatedInventors: Daniel Codazzi, Jean-Yves Mioque, Bernard Montaron
